• Warning: High brightness projector: This projector embeds high brightness (radiance) lasers; this laser
light is processed through the projectors optical path. Native laser light is not accessible by the end user in
any use case. The light exiting the projection lens has been diffused within the optical path, representing a
larger source and lower radiance value than native laser light. Nevertheless, when RG3, the projected light
represents a significant risk for the human eye when exposed directly within the beam. This risk is not
specific related to the characteristics of laser light but solely to the high thermal induced energy of the light
source; which is comparable with lamp based systems. When RG3, thermal retinal eye injury is possible
when exposed within the Hazard Distance. The Hazard Distance (HD) is defined from the projection lens
surface towards the position of the projected beam where the irradiance equals the maximum permissible
exposure as described in the chapter
“High Brightness precautions: Hazard Distance”, page 12 .
• Always switch off the projector and disconnect from the mains power supply before attempting to remove
any of the projector covers or access parts inside the projector.
• This product contains no user serviceable parts. Attempts to modify/replace mechanics or electronics
inside the housing or compartments will violate any warranties and may be hazardous.
• For correct physical installation, refer to the Installation manual.
• Only place the projector on a stable surface or mount it securely using an approved ceiling-mount.
• Exposure to UV radiation: Some medications are known to make individuals extra sensitive to UV
radiation. The American Conference of Governmental Industrial Hygienists (ACGIH) recommends
occupational UV exposure for an-8 hour day to be less than 0,1 micro-watts per square centimeters of
effective UV radiation. An evaluation of the workplace is advised to assure employees are not exposed to
cumulative radiation levels exceeding these government guidelines. The exposer of this UV radiation is
allowed for only 1 hour per day for maintenance and service persons.
To prevent fire hazard
• Do not place flammable or combustible materials near the projector!
• Barco large screen projection products are designed and manufactured to meet the most stringent safety
regulations. This projector radiates heat on its external surfaces and from ventilation ducts during normal
operation, which is both normal and safe. Exposing flammable or combustible materials into close
proximity of this projector could result in the spontaneous ignition of that material, resulting in a fire. For this
reason, it is absolutely necessary to leave an “exclusion zone” around all external surfaces of the projector
whereby no flammable or combustible materials are present. The exclusion zone on the lens side must be
at least 100 cm (39.4”). The exclusion zone on all other projector sides must be not less than 50 cm
(19.7”).
• Do not cover the projector or the lens with any material while the projector is in operation.
• Keep flammable and combustible materials away from the projector at all times.
• Mount the projector in a well-ventilated area away from sources of ignition and out of direct sun light.
• Never expose the projector to rain or moisture. In the event of fire, use sand, CO2 or dry powder fire
extinguishers. Never use water on an electrical fire.
• Always have service performed on this projector by authorized Barco service personnel. Always insist on
genuine Barco replacement parts. Never use non- Barco replacement parts as they may degrade the
safety of this projector.
• Slots and openings in this equipment are provided for ventilation. To ensure reliable operation of the
projector and to protect it from overheating, these openings must not be blocked or covered. The openings
should never be blocked by placing the projector too close to walls, or other similar surface. This projector
should never be placed near or over a radiator or heat register. This projector should not be placed in a
built-in installation or enclosure unless proper ventilation is provided.
• Projection rooms must be well ventilated or cooled in order to avoid build up of heat.
• Let the projector cool down completely before storing. Remove cord from the projector when storing.
To prevent projector damage
• Always remove lens cap before switching on the projector. If the lens cap is not removed, it may melt due
to the high energy light emitted through the lens. Melting the lens cap may permanently damage the
surface of the projection lens.
• Cleaning the booth area would be monthly minimum. Neglecting this could result in disrupting the air flow
inside the projector, causing overheating. Overheating may lead to the projector shutting down during
operation.
• The projector must always be installed in a manner which ensures free flow of air into its air inlets and
unimpeded evacuation of the hot air from its cooling system.
